In the firststate, the first operating portion 112 a of the input module 112 isengaged with the base 111 through the switching mechanism 130, whereinthe spring 140 is compressed by the first operating portion 112 a of theinput module 112, and the compressed spring 140 stores elastic potentialenergy.

For example, the base 111 has a recess 111 d in communication with thesliding slot 111 a, and the spring 140 is located in the recess 111 d.On the other hand, the first operating portion 112 a of the input module112 has a positioning protrusion 112 c configured to be inserted in therecess 111 d. In the first state, the positioning protrusion 112 c isinserted in the recess 111 d, which is used to abut against and compressthe spring 140.

Specifically, the switching mechanism 130 includes an engaging member131 and a button 132, wherein the engaging member 131 is slidablydisposed at the first operating portion 112 a of the input module 112,and the button 132 includes a pressing portion exposed from the firstoperating portion 112 a of the input module 112 for a user to operateconveniently. On the other hand, the button 132 further includes a touchportion located between the first operating portion 112 a of the inputmodule 112 and the base 111 to contact the engaging member 131. The base111 has a locking slot 111 e in communication with the sliding slot 111a, and in the first state, the engaging member 131 is engaged with thelocking slot 111 e to prevent the input module 112 from arbitrarilysiding relative to the base 111.

On the other hand, the sliding mechanism 150 includes a rack 151 and agear set 152 engaged with the rack 151, wherein the rack 151 is mountedto the first operating portion 112 a of the input module 112, and anextension direction of the rack 151 is parallel to the sliding directionSD. The gear set 152 is slidably disposed at the base 111. Based on anengaging relationship between the rack 151 and the gear set 152, thegear set 152 may slide along with the input module 112 and the rack 151relative to the base 111, but the gear set 152 is only allowed to sliderelative to the base 111 within a specific sliding stroke.

In the present embodiment, the gear set 152 includes a gear base 152 aand a gear 152 b pivoted to the gear base 152 a, and the gear 152 b isengaged with the rack 151. Specifically, the gear base 152 a is slidablydisposed at the base 111, wherein the base 111 has a limiting post 111f, and the gear base 152 a has a sliding slot 152 c. The limiting post111 f is inserted in the sliding slot 152 c, so as to limit the slidingstroke that the gear base 152 slides relative to the base 111. In thefirst state, the limiting post 111 f is located at a first stroke endpoint P1 of the sliding slot 152 c.

FIG. 2A is a schematic top view showing the portable electronic devicein a second state according to an embodiment of the invention. FIG. 2Bis a schematic partial cross-sectional view taken along a section lineL-L in FIG. 2A. FIG. 2C is a schematic partial cross-sectional viewtaken along a section line M-M in FIG. 2A. Referring to FIG. 1E to FIG.2B, once the engaging relationship between the first operating portion112 a of the input module 112 and the base 111 is disengaged by theswitching mechanism 130, the elastic potential energy of the spring 140may be released to push the positioning protrusion 112 c, such that theinput module 112 slides relative to the base 111 along the slidingdirection SD, and a part of the second operating portion 112 b slidesout of the base 111 from the exit 111 c.

In this circumstance, the positioning protrusion 112 c is moved out ofthe recess 111 d, and a sufficiently large gap may be created betweenthe first operating portion 112 a and the side wall 111 b for the userto put a finger into the gap and push the first operating portion 112 a,such that the input module 112 sides relative to the base 111.Alternatively, the user's finger may pull the part of the secondoperating portion 112 b which slides out of the base 111, such that theinput module 112 sides relative to the base 111.

Specifically, when the user presses the button 132, the button 132 whichis moved downward pushes the engaging member 131 for the engaging member131 to slide relative to the first operating portion 112 a and move outof the locking slot 111 e, so as to disengage the engaging relationshipbetween the first operating portion 112 a of the input module 112 andthe base 111. In order to ensure a touch relationship between the button132 and the engaging member 131, the engaging member 131 has a firstslot 131 a, and a part of the button 132 is located in the first slot131 a. For example, the button 132 may not only drive the engagingmember 131 to slide, but also be assembled with other function buttons(e.g., a turbo key).

On the other hand, the switching mechanism 130 further includes arestoring member 133. The restoring member 133 may be a spring, and twoends of the restoring member 133 are respectively connected with thefirst operating portion 112 a of the input module 112 and the engagingmember 131. For example, the engaging member 131 further has a secondslot 131 b, and the first operating portion 112 a of the input module112 has a limit protrusion 112 d inserted in the second slot 131 b. Thetwo ends of the restoring member 133 are respectively connected with thelimit protrusion 112 d and an inner wall surface 131 c of the secondslot 131 b. When the engaging member 131 is pushed by the button 132 tomove the engaging member 131 out of the locking slot 111 e, the innerwall surface 131 c of the second slot 131 b moves toward the limitprotrusion 112 d to compress the restoring member 133. When the engagingmember 131 is no longer pushed by the button 132, the inner wall surface131 c of the second slot 131 b is pushed by an elastic restoring forceof the restoring member 133, such that the engaging member 131 slidesback to its initial location. It may be understood that the restoringmember 133 may also be used to ensure that the engaging member 131 isengaged with the locking slot 111 e.

Referring to FIG. 2A to FIG. 2C, when the input module 112 is pushed bythe spring 140 to slide relative to the base 111 along the slidingdirection SD for the part of the second operating portion 121 b to sideout of the base from the exit 110 c, the gear set 152 may slide alongwith the input module 112 and the rack 151 relative to the base 111, andthe gear set 152 does not stop sliding along with the input module 112and the rack 151 relative to the base 111 until the limiting post 111 fmoves to a second stroke end point P2 of the sliding slot 152 c.

FIG. 3 is a schematic top view showing the portable electronic device ina third state according to an embodiment of the invention. Referring toFIG. 2A, FIG. 2C and FIG. 3, after the part of the second operatingportion 112 b slides out of the base 111 from the exit 111 c, the usermay push the first operating portion 112 a or pull the second operatingportion 112 b, such that the input module 112 slides relative to thebase 111 through the cooperation of the rack 151 and the gear 152 b, andthe entire second operating portion 112 b slides out of the base 111. Inthis circumstance, the second operating portion 112 b may tilt withrespect to the first operating portion 112 a to provide the user withdifferent operation modes. On the other hand, the input module 112 sidesrelative to the base 111 and moves away from a location directly above aheat dissipation portion of the base 111, such that the heat dissipationportion is exposed to the outside, and a heat dissipation efficiency ofthe portable electronic device 100 is increased.

Based on the above, in the portable electronic device of the invention,the input module can be driven by the elastic force for the input moduleto partially slide out of the base, thereby providing the user with apoint of force application to grab or push the input module, which isfavorable for the user to pull or push the input module and to switchthe portable electronic device to different operation modes. Thus, forthe user, the portable electronic device of the invention has excellentoperational flexibility and operational convenience. On the other hand,the user can disengage the engaging relationship between the inputmodule and the base, as well as push the input module by the spring onlyby pressing the button. Thus, the operation method can be easy andintuitive.
